Can two CPUs hold two "different" spin locks simultaneously at same time?
So...does this mean: a sigle(uniprocessor) CPU cannot hold two "different" spinlocks at the same time?
So...does this mean: the number of spinlocks on a single CPU cannot be > 1.
PS:"different" implying spinlock associated with different memory resources.
Does anybody know how spinlocks work internally? ...I mean, do they freeze bus during test set operations? I have googled but no absolute answer.
